Hi IoTas:
Let you know, finally I updated the firmware successfully after a lot of hard work with new MCU. Thanks got your help again. Without your help I have no way to go. I used a USB to UART adapter to make it happened write this firmware to the MCU without use official updates hardware kit(from Marantz which discontinued product). I post some pictures here. Also share this results to contribute this forum for those who are dealing with AVR MCU.
But additional problem is no HDMI no audio. I checked it is Sil9033 HDMI receiver...Leave a comment:
